This system uses a rate gyro to detect the angular velocity of the aircraft around the vertical axis (yaw). Understanding the Aerodynamic Forces The phenomenon occurs due to a specific interaction between directional stability and lateral stability.

Additionally, improper maintenance, such as a faulty or misaligned rudder, can exacerbate the issue. The standard method for controlling an aircraft is not to fight the motion with brute force on the controls, but to use yaw damping.
The Role of the Yaw Damper Modern aircraft are equipped with a system known as a yaw damper, which is a critical component of the autopilot system. The distance between the center of gravity and the vertical stabilizer, known as the lever arm, plays a significant role.

The Mechanics of the Motion Imagine an aircraft begins a slight roll to the right. Aircraft with a long fuselage and a high-mounted vertical stabilizer, such as swept-wing jets, are often more prone to the phenomenon.
